Can you clarify what you mean when you say "Amazon marketing?" Do you mean being featured by Amazon, or algorithmically suggested to readers of other books, or something else altogether? I am not asking snarkily; I am genuinely curious. I'm contemplating self-publishing, but I'm aware that Amazon is a pretty noisy landscape. If there are ways to power one's signal through the noise, I'm interested in learning about them.
